USING COMPRESSION
The meters on the TRIPLE•C are excellent tools to achieve
this. Lets have a closer look at the meters.
When no signal passes through the unit the gain is
illustrated like this:
Try turning the Make-up Level knob to change the level.
If no compression is applied you are now actually changing
the Output level.
When the signal is processed/compressed the Output level
is reduced. The amount of gain reduction/compression
applied is illustrated via the via the meters like this:
(example in Multi-band mode)
To achieve the same Output level on the processed signal
as on the unprocessed signal simply turn up the Makeup
Gain level knob until the max gain reduction is at the 0dB
marker.
This will look approximately like this :
This is how easy it is to apply Make-up gain using the
TRIPLE•C.
Hard Compression of Vocal Tracks.
By compressing vocal source material hard a very distinct
and precise but less dynamic track will be the result. For
this purpose we need the Compressor to work practically
all the time. Therefore the Threshold must be set rather
low, the Ratio rather high and the Attack time short. The
release time setting again depends on what it is you would
like to achieve. If you with this “hard compression scenario”
wishes to hear e.g. the singer taking the next breath in
between his/hers actual singing a short Release time
should be your choice. A long release time on the other
hand would compensate for this
Guideline Settings
Ratio: 5-6:1
Attack: 5ms
Release: 100ms
Controlling Percussive Material
When using compression on e.g. a snare drum entirely
different aspects are to be taken in consideration compared
to vocal processing. A drum has a sharp attack but almost
no durance. For the Compressor to take effect at all a
really short Attack time is essential. The Threshold can be
set relatively low as you probably want to process all snare-
drum hits. The Ratio setting for this application is really
where you can add different characteristics on the signal.
The higher a Ratio setting the more flat but distinct a sound
you can create. Too high a Ratio setting allows only a small
amount of the source materials original characteristics to
be maintained.
Guideline Settings
Ratio: 4:1
Attack: 1.0 ms
Release: 100ms
Makeup Gain
When a signal is compressed the max Output level of the
signal is reduced. Since it is a reduction in dynamic
content and not a gain-reduction that is the object of
applying compression a make-up gain is necessary to lift
the signal to appropriate level.
Also when using the bypass function for comparing the
unprocessed signal with the processed signal equal level
for these modes is essential.
